K-65 residues are the very radioactive mill residues resulting from a uniquely concentrated uranium ore discovered before WW II in Katanga province (Shinkolobwe) of the Democratic Republic of the Congo (formerly called the Belgian Congo).

Karl-Ludwig Kratz

radioactive ones (thorium and uranium) the age of these stars can be determined to about 13 billion years (see Sneden's Star, Cayrel's Star, Kratz's Star, Frebel's Star (HE 1523-0901)).
